Sloane Stephens
Most of Sloane’s sponsorship deals were coming to an end in 2017… So she decided to earn herself some better ones by winning her first Grand Slam title in the same year. This opened the door to so impressive new deals, including ones with Nike and Rolex. Her endorsements of around $5.5 million are just under her prize winnings of $5.7 million.
Caroline Wozniacki
She’s one of the most famous female athletes in the world, yet her prize money and endorsement deals are less than you may think. Her prize money was an estimated $7 million last year, which was topped up by $6 million in endorsements with companies like Adidas and Usana.

Serena Williams
The only female athletes to make it into the Forbes 100 is Serena Williams. While she may not be raking in the prize money like some of the others on this list, it’s her endorsements that bring in the big bucks – an estimated $18 million! She’s also made over $86 million in prize money since she started playing tennis.
While they’re still making million, it’s clear to see that female athletes aren’t paid as much as their male counterparts. Eight out of the top ten are in tennis, proving that’s definitely where the money is. Perhaps it’s time to shake things up a little? We certainly think so!
